The term childhood disease refers to disease that is contracted or becomes symptomatic before the age of 18 or 21 years old. Many of these diseases can also be contracted by adults. Some childhood diseases include:
Respiratory disease is a common and significant cause of illness and death around the world. In the US, approximately one billion common colds occur each year. [29] A study found that in 2010, there were approximately 6.8 million emergency department visits for respiratory disorders in the U.S. for patients under the age of 18. [30]
Severe disease is rare in people who are usually healthy. [11] Around 10% of respiratory infections in children are caused by adenoviruses. [11] Most are mild and by the age of 10-years, most children have had at least one adenovirus infection. [5] Adenoviruses are the most common viruses causing an inflamed throat.
The same is true for RSV, a common respiratory virus that's usually more like a cold for adults but can be dangerous for young children, babies and older adults with chronic medical conditions.
Common causes of viral pneumonia are: Influenza virus A and B [5] Respiratory syncytial virus (RSV) [5] Human parainfluenza viruses (in children) [5] Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) [6] Rarer viruses that commonly result in pneumonia include: Adenoviruses (in military recruits) [5] Metapneumovirus [7]
Most common causes for children include asthma, respiratory tract infections and GERD. An estimation of between one and 21% of children suffer from chronic cough. [ 2 ] [ 32 ] [ 33 ] Causes typically diagnosed include viral bronchitis, post-infectious cough, cough-variant asthma, upper airway cough syndrome, psychogenic cough and GERD.
Specifically, in the U.S., RSV most commonly causes bronchiolitis (inflammation of the small airways in the lungs) in children younger than 1 year old and sends approximately 58,000 children under ...
The lower respiratory tract consists of the trachea (windpipe), bronchial tubes, bronchioles, and the lungs. [6] Lower respiratory tract infections (LRIs) are generally more severe than upper respiratory infections. LRIs are the leading cause of death among all infectious diseases. [7] The two most common LRIs are bronchitis and pneumonia. [8]
